Given numbers are 401,391,851,102
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,391,851,102 is 34807602.
Find LCM of 401,391,851,102 with Prime Factorization
| 17 | 401, 391, 851, 102 |
| 23 | 401, 23, 851, 6 |
| 401, 1, 37, 6 |
Multiply the prime numbers at the bottom and the left side.
17 x 23 x 401 x 1 x 37 x 6 = 34807602
Therefore, the lowest common multiple of 401,391,851,102 is 34807602.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
401 x 391 x 851 x 102 = 13609772382
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
401 : 1, 401
391 : 1, 17, 23, 391
851 : 1, 23, 37, 851
102 : 1, 2, 3, 6, 17, 34, 51, 102
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,391,851,102, is 1.
Now, the common factors can be found like this.
401:401
391:17x 23
851:23x 37
102:2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 23 = 391
Therefore, the value for common factors is 391.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 13609772382/(1x391)
LCM = 13609772382/391
LCM = 34807602
Thus, we can understand that the LCM of 401,391,851,102 is 34807602.
